ubuntu 11.10 的有線網路不能用，但是我網路線插別台卻能用，ip位置、網路罩子、通訊閘道、DNS 都是設定一樣。

從終端機
sudo ifconfig -a
把結果貼上來看看

你如果 把 網路線插別台
得到的 IPv4 也是 10.10.154.18 嗎

我都是用固定ip位置，所以不管插哪一台都是一樣的

1. sudo route -n
貼上來
2. ping -c 5 127..0.0.1
3. ping -c 5 localhost
4. ping -c 5 10.10.154.18
5. ping -c 5 10.10.154.254
6. ping -c 5 www.ubuntu-tw.org
把不正常回應的貼上來

2. ping -c 5 127..0.0.1

抱歉 這個打錯了 應該是
2. ping -c 5 127.0.0.1
不過 這個應該沒問題了

補（漏了）
4. ping -c 5 10.10.154.18
增加

8. ping -c 5 168.95.1.1
9. ping -c 5 140.138.145.240
哪一個回應不正常 copy 貼上來

我要怎麼看才算不正常?

我這台是新筆電，會不會是網卡驅動的問題?但是我的燈都有亮。
